Lighting Retrofit Provides Virus-Fighting Capabilities

The Vernon Area Public Library, located in Lincolnshire, Ill., recently worked with Milwaukee-based Johnson Controls to install ultraviolet (UV) lighting in two of the library's existing air handling units (AHUs), which serve the majority of the occupied space. As a result, airborne contaminants, including the virus that causes COVID-19, will be neutralized, while improving the building's indoor air quality (IAQ) and creating a safer place for employees and visitors upon reopening. Partially funded by the CARES Act, this project is part of the library's ongoing strategy to provide a class-leading environment in the community. Additionally, it was the company's first library project in the Chicago area to implement UV lighting as part of its IAQ improvement strategy, says Catherine Hawn, account representative of building services of the company.

UV lighting has proven to be effective in airborne disinfection, which kills contaminants and pathogens including the COVID-19 virus. Implementing UV lighting grids in the library's existing AHUs will provide long-term benefits to occupants through a 99.99% reduction in bacteria, rhinoviruses, and coronaviruses. The company also installed advanced MERV 13 filters to provide a comprehensive decontamination strategy. 

“Our goal has been to do everything within our power to keep our employees and the community safe,” says Stephen Territo, head of library operations at the Vernon Area Public Library. “The science is clear about the importance of addressing airborne transmission. We are pleased to be able to put this innovative and effective solution in place.”
